Painted High Strength Ss Self Threading Bolts For Metal With Rubber Washer HDG Mechanical

      Hex Washer Head Self Drilling Screws(HWH) or Hex Washer Flange Head (HWF) Self   drilling screws are used in metal applications. Self-Drilling Screws, also called as Tek screws,  eliminate the need for a pre-drilled hole.

      The Self drilling screws, not like the self tapping screws, does not require a pre-drilled hole before installing. It can drill into the metal or iron board directly……

        Through ordinary passivation, the antioxidant and rust-proof capacity of self drilling screws which our factory produced increased by more than 5 times, and the neutral salt spray test has achieved more than 50 hours. Extending the working life and increasing the reliability.

• High Performance – Continuous thread design up to drilling point maximizes pullout performance and shear strength.
• Precision – Drilling these screws is achieved in a single process thus eliminating the need of alignment or pre-drilled holes and thus ensuring precision.
• Easy and Smooth Tapping – Its smooth thread allows easy and self tapping through the structure.
• Easy to Use with Minimal Efforts – Design of these screws is so engineered that unskilled amateur can use them with minimal efforts.
• Time Saving – Using these screws saves time by eliminating the need of alignment or pre-drilled holes.
• Dual Functionality – Allows fastening to both, timber and steel.
• Minimal Wastage – Reduces Wastage
